2nd to 3rd long shift.....

[JeepDad74]

Ok so I'm running a 315/70/17 on my 2020 Gladiator and the trans likes to delay the shift on the 2/3 . Has anyone else seen this issue and what did you do about it.

Did you just install them?
Which Gladiator do you have? (so we know the gear ratio, unless you changed that as well)
Did you go in and tell the BCM (body control module) that you have bigger tires so it can remap things?

If you just installed those tires, and this just started, and you did not go in and tell it of the larger tires - that may be your answer. (You need a dealer to do it, or use JSCAN, AlfaOBD or a tazer)

We need more info - you are leaving much out, leaving us guessing.

It's been about a month and I ordered my flashcal that should be here tomorrow. Sorry I've got the sport model

Sounds like you already know what you should do.

My ‘21 is running 39’s with Tazer set to the proper tire size, speedo is spot on. I drag from 2 to 3rd constantly and have to lift the throttle and get back into it to kick over. Ive been patient with it because im expecting the call anyday now that my Fusion 60’s with 5.13s will be getting delivered. I hope this squares it away bit either way because I know it does it sometimes, I just take it easy
